Application filed December 15; 1930. Serial No. 502,393.

This invention relates to eye goggles, and more particularly goggles of a character for usage under conditions involving more or less activity, and under unfavorable conditions; and it is among the objects of the invention to provide a construction durable and yet readily adjustable to wearing conditions. A further. object is the provision of means for inhibiting steaming or fogging of the lenses. Other objects and advantages will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention, then, com9 prises the features hereinafter fully described and particularly pointed out in the claims, the following description and annexed drawings setting forth in detail certain embodiments of the invention, these being illustrative, however, of but a few of the various ways in which the principle of the invention may be employed.

in said annexed drawings:

Fig. 1 is a plan view, portions being broken away, showing an embodiment of the invention; Fig. 2 is a front elevational view; Fig. 3 is a similar View of a modification; Fig. 4- is an isometric detail, and Fig. 5 is an ele rational view of another modification.

Referring more particularly to the drawings, there is shown a pair of goggle cups 2, 2,

having suitabie transparent members or lenses 8, and provided with bows or a head.- band 4:. Connecting the goggle cups is a bridge, of a character allowing extension in accordance with particular requirements. This may comprise an extensible connecting member 5, as for instance, a coil spring. While in some cases such spring may be relied upon to both hold and limit the positioningof the cups, ordinarily I prefer to include also a means for limiting the extension between the cups and preferably this may take the form of a flexible inextensible member, such as a chain 6, this being conveniently positioned within the coil spring. Desirably, a casing 7 encloses the whole and this may be in the form of a tube, for instance of rubber, of soft or harder character. The casing may be attached to a central portion of the spring, if preferred; for instance by engagement of an enlarged coil 5" (Fig. 1'); The members 5 and 6' may be anchored to. the goggle cups by any convenient means, for instance metallic staples 8, or the like.

Although the goggle cups may have the known ventilating openings, I also OOIltGIIh plate providing connections for supply of a positive air flow for the inhibiting of steaming or fogging of the transparent members or lenses, my investigations having shown that notwithstanding the existence of free ventilation, difficulty is still prone t oi occur,

tor may from time to time, as-necessary,

then simply hold the mouth-piece 12 between his lips and draw in air therethrough, a cur- 7 rent thus being caused to flow from the outside through the ventilating o enings, and

through the goggle cups, there y removingvapor condensed on the lenses. The mouthpiece 12 may advantageously be in the form of a separable nozzle, as for instance by screwthreading engagement, so that new pieces may readlly be substitutedas maybe desired in the event of different users; Instead of employing a mouth-piece for inhalation whereby todraw an air current from the outside across the surfaces of the 1 lenses, I may provide similar action by nose-piece, for instance a housing 13 (see Fig. 3) of'rubber or any suitable material,

to snugly fit over the nose, being connected to the goggle cups by suspending means 14:,

which may be of resilient or spring form, holding the member in position, but without dlscomforting. pressure. The conduits or tubing 11 then connect by a nozzle-piece 12- to the housing 13. With proper adjustment, on inhaling, the housing 13 fits sufficiently closely to substantially prevent intake of air therearound and the inhalation air is ac cordingly drawn through the ventilating openings in the cups and across the surface of the lenses and through the tubing 11, while on exhalation the housing 13 is simply forced away sufficiently to allow due escape of the exhaling breath. If desired, one or more exhalation valves 15 may be applied to the housing, these being simple check-valves,

for instance on the order of a flap-valve opening outwardly.

In cases where desired,instead of operating the air supply tubes by nasal or mouthinhalation, connection by a tube 16 (see Fig.

5) may be made to any suitable source of compressed air, forinstance a small compressible rubber bulb 17. With such latter, an

occasional pumping thereof may be resorted to as required, 1n order to maintaln the lenses clear. By suitable arrangement of the check-valve in the bulb 17, the action may be 'inspiratory, air being drawn through the.

goggle cups from the ventilating openings,

instead of being forced by the bulb through the cups and out through the ventilating mechanism. The particular arrangement in any case is thus a matter of preferred convenience.

Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the means stated in any of the following claims, or the equivalent of such, be

employed. I i r I therefore particularly point out and'distinctly claim as my invention: 7 I

1. Eye goggles, comprising goggle-cups, a nose-bridge including a coil spring, a casing therefor, and a central engagement between said casing and an enlarged coil of the spring. I

'2. Eye goggles, comprising goggle-cups, anose-bridge including an extensible member,

a casing therefor, and means for securing.

said casing to a central portion of said extensible member.

3. Eye goggles, comprising goggle-cups, a

nose-bridge including a coil spring, a casing therefor, and a flexible member limiting the maximum'separation between said goggle-cups. I Y I 4. Eyegoggles, comprising goggle-cups, a nose-br1dge o1n1ng said cups lncludlng a COll spring and a chain therein, and a casing about such spring. 1 V

5. Eyegoggles, comprising goggle-cups, a nose-bridge including a coil spring and a chain therein, a casing about such spring, and a central engagement between'said casing and an enlarged coil of the spring Signed by me this 13th day of December,
